US Wind Power Generation vs US Infant Mortality

US Wind Power Generation and US Infant Mortality correlate at r = -0.69 over 42 years (1983–2024), p < 0.0001. With the time trend removed, r = +0.86. Direction flips without the trend.

Verdict: Direction flips without the trend. The raw correlation is -0.69, but once each series' time trend is removed it becomes 0.86. The year-to-year movements run the opposite way to the long-run trends, so the headline number is misleading.
